Project Description

We're looking for an experienced AI/ML Lead to join and expand our Data and AI Engineering team. This is a hands-on leadership role ideal for those who are passionate about both advancing AI capabilities - particularly LLMs (Large Language Models) and ML systems - and building high-performing engineering teams. You will lead the strategic direction of AI/ML initiatives, mentor junior engineers, and continue to actively contribute to designing and deploying production-grade AI solutions for the life sciences industry.

You'll combine technical excellence with leadership acumen, overseeing the development of intelligent systems, scalable AI infrastructure, and internal platforms while fostering a collaborative, innovative culture within the team. We welcome leaders with deep hands-on experience who thrive in environments that value both technical rigor and people development.

What You'll Do

- Lead and mentor the AI/ML engineering team, fostering a culture of technical excellence, continuous learning, and collaboration.
- Define and communicate the technical vision and roadmap for AI/ML initiatives across the organization.
- Conduct code reviews and architectural reviews to ensure best practices, scalability, and security in AI/ML systems.
- Actively design, build, and deploy LLM-powered applications and internal tools for use cases such as document understanding, process automation, and knowledge retrieval.
- Develop and maintain reusable AI infrastructure and platform components that support application teams (e.g., retrieval-augmented generation, prompt management, model orchestration).
- Oversee the end-to-end lifecycle of ML models: experimentation, evaluation, versioning, and deployment using tools like MLflow and CI/CD pipelines.
- Work with embeddings, vector stores, and similarity search to enable contextual AI responses in production systems.
- Integrate with vector databases (e.g., FAISS, Weaviate, or Pinecone) to support semantic search and information retrieval at scale.
- Collaborate with Data Engineers, Backend Engineers, and other stakeholders to align AI/ML work with business objectives and technical constraints.
- Champion good engineering practices around testing, observability, monitoring, and CI/CD for AI components.
- Guide technical hiring, conduct candidate interviews, and contribute to building a diverse and inclusive team.
- Lead discussions on AI ethics, responsible usage, model explainability, and compliance - especially for regulated use cases in healthcare.
- Contribute to and drive architectural decisions, system design, and strategic product discussions.
- Support team members through career development, performance feedback, and professional growth opportunities.

What We're Looking For

- We believe diverse perspectives and backgrounds lead to better ideas. Even if you don't meet every requirement, we'd still love to hear from you.

Core Experience & Skills

- 5+ years of hands-on experience in AI/ML engineering, with at least 2+ years in a leadership, mentorship, or senior engineering role.
- Proven track record of successfully building and deploying LLM-based systems in production (e.g., GPT, Claude, LLaMA, Mistral, etc.).
- Strong understanding of modern ML infrastructure: experiment tracking, model versioning, and deployment orchestration (MLflow, Weights & Biases, DVC, etc.).
- Hands-on experience with embeddings, vector databases (e.g., FAISS, Weaviate, Pinecone), and semantic search implementations.
- Solid grasp of AI/ML fundamentals: model evaluation, hyperparameter tuning, feature engineering, and performance optimization.
- Demonstrated experience leading technical teams, including hiring, mentoring, performance management, and conflict resolution.
- Experience driving technical strategy, architectural decisions, and cross-functional collaboration with non-technical stakeholders.
- Awareness of AI ethics, responsible AI practices, bias mitigation, and model explainability concerns.
- Strong communication skills with the ability to articulate complex technical concepts to both technical and non-technical audiences.
- Team-first mindset and experience fostering collaborative, agile environments (Scrum or Kanban).
- Professional working proficiency in English.

Nice to Have

- Experience with Docker, Kubernetes, and containerization/orchestration in production environments.
- Expertise in prompt engineering, retrieval-augmented generation (RAG), and frameworks like LangChain or LlamaIndex.
- Experience with cloud infrastructure and MLOps across Azure, AWS, or GCP; cloud-agnostic or multi-cloud experience.
- Background in regulated industries (life sciences, healthcare), especially GxP environments and compliance requirements.
- Familiarity with advanced monitoring, logging, and observability tools for AI/ML workloads in production.
- Experience with distributed systems, big data processing, or complex data pipelines.
- Track record of contributing to open-source projects or publishing research in AI/ML domains.
- Spanish and/or Catalan language skills.
